Presented in full: Gaar Adams’ five-part series detailing his weeklong 2014 expedition in Yemen to track the Arabian leopard – one of the rarest animals in the world. From the Western Highlands to the depths of the Southern Mountains, join the 1,000-kilometer journey from rusted-out pickup trucks with rifle-wielding mango farmers to cave-homes hewn out of sheer cliffs in search of the elusive big cat. With stories of extremism and conflict dominating media coverage of Yemen, take a rare inside look at the ecological surprises nestled amidst the country’s isolated valleys as Adams investigates the barrage of threats assailing some of the most remote and least studied natural environments on the planet.
